Application filed January EC, 1914. Serial No. 813,245.

To all whom it may concern:

Be it known that l, VTALTER D. S'IOCKLY, a citizen of the United, States, residing at Fairmont, in the county of. Marion and State of Test Virginia, have invented certain new and useful Improvements in Mine and durable manner; and particularly to that class of such cars as employ tubular axles for the purpose of insuring lubrication for maximum time with minimum at' tention.

The invention has for its object to provide an improved construction of self-lubricating wheel and axle, and one which will be very simple, in construction, economical in the consumptien of lubricant and very durable in use. Smne of the difliculties that have to be dealt with in acccinplishing the object stated are the mnstant distribution of lubricant only in such 1n=1nportions ee -the same shall be needed in relievingthe natural friction of the wheels on the axle, in order to avoid waste, and a construction of Wheel which when in place on the axle will exclude grit and foreign substal'ices which develop excessive wear of the bearings. The present invention zurcomplishes these ebyects in an economical and edicient manner, by means of the constructi m hereinafter fully described and particularly pointed out in the sub-joined. claims, reference being bad to the accompanying drawing, in Which Figure 1 is a vertical axial section through a portion of a. mine car with its axle and wheels mounted thereon; 2 is a detail "View of a portion of Fig. I seen from above;

Fig. 3 is a section on the line 3 3", Fig. 1; Fig. =-l is a section on the line -l* 4, Fig. 1 Fig. 5 is a detail View of the yoke holder and a portion of the bolster upon which the yoke holder is preferably mounted, and Fig. 6 is a detail view oft/he dannning ring which is introduced between each wheel and the axle, tor the purpose of hunting the escape of lubricant.

A. represents, by way of suggestion, a vehicle body, and 1 is a tubular axle mounted thereon. The axle is secured in place with freedom of rotation as well as longitudinal. movement, and this is preferably accom plished by means of an inverted channel bolster 2 and the clips or hangers 3. The latter'are constructed to prevent the axle from dropping down in the event. of the wheels being lifted 'momentarily from the, rails and provided with shoulders 3 through which they support the bolster 2, as well as cars 3 to receive attaching bolts 3".

l represents the Wheels which fit the outer ends of the axles, but have closed hubs so that they form hermetic end closures for the tubular axles; their hearing boxes being provided with enlargements 4Q surrounding the extreme outer end of the axle to facilitate radial flow of the lubricant under centrifugal action; these enlargements extending backward slightly from the ends of the axle inorder to deliver the lubricant to the cylindrical surface of the axle spindleshnd cause it to flow between the Wheel and axle under the combined influence of the rotating Wheel.

and the pressure of other lubricant that is behind it. To restrict this flow of lulu'icant from the inner ends 01 the hubs, packing rings 49 are provided within the hubs and tightly siu'rounding the axles, and these rings are provided with escape openin s 4 which are regulated in size so as to pimit the escape of the lubricant only'about as fast as it is consumed. The rings i serve the further purpose'of excluding dust and grit from the bearings.

The wheels are secured against displacement from the axle and are also effectively limited in outward movement relatively to the car body and to each other by means of the yoke holders 2* mounted upon the ends of the bolster 2 and provided with the abuttingshoulders :2, the lugs 2 and the seats 9, which latter receive the yokes 5 in posiage in trout ot the flanges l of v tion to cap' the wheels; lhe yokes have at one end heads 5 and lugs 5 which adapt them ti) ment of he flanges 4 between the yokes 5 and the shoulders 2.

The Wheels being definitely spaced apart by a tying means, such as the bolster 2, exterior to the axle, the axle can be left free to reciprocate until its ends are arrested by the closed hubs of the wheels, which recipro- I action until it enters the annular chamber between the end of the axle and the wheel,

whence it'flows into the bearings to be lubricated. The packing ring prevents a free escape. of the lubricant and retards theflow.

It, however. permits escape of spent lubricant through the" opening 4r of the packing ring. Inasmuch as the opening 4 can be readily adjusted .to such size as experience dictates to be'de sirable with the particular lubricant used, said ring affords a very efficient and simple methodfof reducing waste of lubricant. The reservoir alforded by the tubular axle may be filled in any suitable manner, as for instance by an opening 4 in one of the wheels, which being thereafter I closed, leaves the wheels in principle hering influences explained. I

I claim 1. In a vehicle, a floating hollow axle and wheels independently secured relatively to and revolubly mounted on said axle and free to have a limited longitudinal movement on said axle, said wheels having closed hubs. I

2. A running gear for vehicles including a hollow a'xle forming a lubricant reservoir and having wheel bearings at each end, wheels independently and revolubly mounted on the bearings of said axle, the axle box of the wheels being closed at their outer ends by an end wall whichlies when in assembled position, in close proximity to the end of the floating axle, whereby the. said end wall and the end of the-axle coact- 'meticallv closed and subject only to thefeedtofeed the lubricant from the axle to the axle bearings witli'inthe hub of the wheel.

3,. Iii a wheeled vehicle, a reservoir axle, a wheel having a closed hub fitting over the end' of said axle, and'a packing ring between the hub aiid'tl e axle near the inner end of the hub. i

' 4. In a wheeled vehicle, a reservoir axle, a wheel having a closed hub fitting over the end of said axle, and a packing ring between the hub and the axle near the inner end of the hub, said ring having an opening to per having an open end and a wheel having a.

hub' with acloscd end fitting over the open' 1 end of the axle said hub having a diainetrlcally enlarged. chamber for conducting lubricant from the hollow of the axle on to the outer surface of the same.

6. In a wheeled vehicle, the combination of an axle, a wheel having a hub with a closed outer end, and a shouldered inner end, a yoke holder comprising a pair of ears pro-.

jecting on opposite sides of the wheel hub,

and a yoke extending through Sflld ears and over the wheel hub in front of said shoulder; said yoke also having a laterally prQ ecting .head embracing one of said lugs.

7. In a wheeled vehicle. a tubular axle, closed end hubs fitting over the ends of said axle, a member extending across-the vehicle.

outside of said axle, and yokes carried by said member and engaging the respective wheel hubs. 1 g

8. In a wheeled vehicle, the combination of a tubular axle, a channeled bolster extending across the vehicle and receiving said axle, yoke carriers formed-on the ends of the bolster, yokes supported by said yoke carriers and wheels fitted to the ends of the axle and having shoulders engaged by said yokes. 1 The foregoing specification signed at Fairmont, West Virginia, this 7th day of January, 1914. v r
